1. What is the Volume of a Circular Pool?

Definition: This calculator computes the volume of a perfectly cylindrical pool based on its radius and depth.

Purpose: It helps pool owners, builders, and maintenance professionals determine water capacity for filling, chemical treatment, and construction planning.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \pi \times r^2 \times D \]

Where:

\( V \) — Volume of the pool (cubic units)
\( r \) — Radius of the pool (same units as depth)
\( D \) — Depth of the pool (same units as radius)
\( \pi \) — Mathematical constant (~3.14159)

Explanation: The formula calculates the volume of a perfect cylinder by multiplying the area of the circular base (πr²) by the depth.

3. Importance of Pool Volume Calculation

Details: Accurate volume calculations ensure proper chemical dosing, correct pump sizing, and accurate water replacement estimates.

4. Using the Calculator

Tips: Enter the pool radius and depth in the same units (feet, meters, etc.). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What if my pool isn't perfectly cylindrical?
A: This calculator assumes perfect cylindrical shape. For other shapes, use different formulas or divide complex shapes into simpler components.

Q2: How do I measure radius if I only know diameter?
A: Simply divide the diameter by 2 to get the radius.

Q3: What units should I use?
A: Any consistent unit (feet, meters, yards) can be used as long as both radius and depth use the same unit.

Q4: How does depth variation affect the calculation?
A: For pools with varying depths, use the average depth or calculate sections separately.

Q5: How can I convert cubic units to gallons/liters?
A: Multiply cubic feet by 7.48 for US gallons, or cubic meters by 1000 for liters.
